@Malone232 hi Stephanie, you can eat anything anybody eats if you want and if you know how to use insulin - including vitamins… I am not a big fan, I think you can get everything you need from diet, and I do not care for the regulations regarding “vitamins” in the US. however t1’s can get low on B and D, and so when my actual blood tests show a deficiency, I take either B or D or both. good luck.
